I think this mostly confuses implementation with architecture. Simple test: Are you using/getting different email addresses when you use these different modes of access? Probably not. That said, note that John Levine's description of his signing model nicely provides an example of having different UAID values, depending on the author's means of access. In this case, he's decided that there is in fact some real utility in making exactly the distinction you raise. So it's plausible, but no it's not necessary. -- Dave Crocker Brandenburg InternetWorking bbiw.net _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
